A Master List of Non-Stellar Objects

Flash hyperspectral imaging of non-stellar astronomical objects

There are certain classes of astronomical objects that have rather involved spectra that can also be a composite of a number of different spectral signatures, as well as spatial characteristics that can be used for identification and analysis. Such objects include galaxies and quasars with active nuclei, colliding / interacting galaxies, and globular cluster systems around our own Milky Way and...

Non-thermal emission from Massive Young Stellar Objects

In the young stellar object (YSO) phase of their lives, massive stars drive bi-polar molecular outflows. These outflows produce beautiful, often hourglass shaped, cavities. The central star possesses a powerful stellar wind (v ∼ 2000 kms), and possibly a dense equatorial disk wind (v ∼ 400 kms), which collide with the inner surface of the bi-polar cavity and produces hot (T ∼ 10−10 K) shocked p...

Development of a Master Health Facility List in Nigeria

UNLABELLED Abstract. INTRODUCTION Routine Health Information Systems (RHIS) are increasingly transitioning to electronic platforms in several developing countries. Establishment of a Master Facility List (MFL) to standardize the allocation of unique identifiers for health facilities can overcome identification issues and support health facility management. The Nigerian Federal Ministry of Hea...

List Objects with Algebraic Structure

We introduce and study the notion of list object with algebraic structure. The first key aspect of our development is that the notion of list object is considered in the context of monoidal structure; the second key aspect is that we further equip list objects with algebraic structure in this setting. Within our framework, we observe that list objects give rise to free monoids and moreover show...
